Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597022, here are decompositions:

19 + 31597003 = 31597022
31 + 31596991 = 31597022
73 + 31596949 = 31597022
109 + 31596913 = 31597022
139 + 31596883 = 31597022
229 + 31596793 = 31597022
271 + 31596751 = 31597022
313 + 31596709 = 31597022

Showing the first eight; more decompositions exist.
